Bus bars for 3P4S battery
* The bus bars that come with the cells would be very good for tying the cells end to end, as 3 bars have plenty of capacity. However, they won''t go end-to-end, as the batteries are two-hole, and the bus bars are drilled for side-to-side. Rats! * Great picture. But I''m confused. I don''t see any bus bars or connections of any sort.

Using 4/0AWG wire from my battery bank to bus bar, What gauge
That means that at full load it needs to draw 3000W/.9=3333.3W from the battery. When the battery is low, it takes 3333.3W/12V= 277.8Amps. (That is a lot). The fusing on that should be 277.8A x 1.25=347.2A Round that up to 350A. * Your battery fuse should be 350A * The smallest Marine grade wire between the battery and the inverter should be 3/0
Charge controller to +bus bar or direct to battery?
Is it better to connect my charge controller directly to my diy lithium batteries or can I use the same 250 amp positive bus bar that my 12 vdc distribution panel and inverter are going to be connected to? All with individual fusing between bus bar and device. All negatives going to shunt for Victron 712 battery meter.
Fusing and busbars
Surface-mount breakers it is! A 30-amp on each SCC and a 70-amp on the charger. Additional plain battery disconnect switches on the battery (between fuse and busbar) and the rooftop solar panel line coming in to the MPPT SCC. That leaves the fan/thermostat and I have a feeling an inline 1-5amp mini-fuse or glass fuse should be plenty.
